Upon request, the Building Inspector may issue
a temporary certificate of occupancy for a building or structure,
or part thereof, before the entire work covered by the building permit
shall have been completed, provided that such portion or portions
as have been completed may be occupied safely without endangering
life or the public welfare.
Whenever there are reasonable grounds to believe
that any material, construction, equipment or assembly does not conform
to the requirements of the applicable building laws, ordinances or
regulations, the Building Inspector may require the same to be subjected
to tests in order to furnish proof of such compliance. All such tests
shall be made at the expense of the owner or his agent.
